  • Method for producing adipamide as intermediate for production of raw material for bio-based nylon
    Patent number: 10829439
    Abstract: Disclosed is a method for producing adipamide, which may include the steps of: (a) reacting glucose, nitric acid (HNO3), sodium nitrite (NaNO2) and potassium hydroxide (KOH) to produce a glucaric acid potassium salt, (b) producing glucamide by reacting the glucaric acid potassium salt, with an acidic solution and removing a potassium ion from the glucaric acid potassium salt, (c) preparing an reaction admixture by adding the glucamide and a catalyst to hydrogen halide and acetic acid, and (d) treating the reaction admixture with hydrogen gas in a reactor thereby producing the adipamide.

  • Method for manufacturing adipic acid using biomass
    Patent number: 10414710
    Abstract: A method for preparing bio adipic acid includes steps of (a) preparing a glucaric acid potassium salt by mixing and reacting glucose, nitric acid (HNO3), sodium nitrite (NaNO2) and potassium hydroxide (KOH), (b) preparing glucamide from the glucaric acid potassium salt prepared in the step (a), (c) preparing 2,4-hexadiene diamide by performing a deoxydehydration reaction on the glucamide prepared in the step (b), (d) preparing adipamide by introducing the 2,4-hexadiene diamide prepared in the step (c), hydrogen and a hydrogenation catalyst to a reactor and performing a hydrogenation reaction, and (e) preparing adipic acid by introducing the adipamide prepared in the step (d) and an aqueous hydrochloric acid solution to a reactor and then performing a hydrolysis reaction at a specific temperature.
